"Application filed March s, 1926. ,senarno; 93,063.;

This invention relates to improvements in closure caps, and more particularly to the dependingannular flange orband portion which. retains a cover/disk in engagement with the mouthof a=-container,itlie primary object-.beingfito soq form thisflange asiio eliminate obj ectionableprojections and other objectionable surface irregularities; ordinae rily found. at the point; "of" connection be; tween the meeting ends-of the-.bandnsed in the formation of the flangei Other objects will bev in part obviousand inpa rtflpointed.outihereinafter.

iI'n' the accompanyingdrawings forminga part of this application and illustrating; the preferred embodiment :of" my invention Fig. l is a detailed perspective view of a screw cap flange, the closure disk being eliminated for the sake of clarity.

Fig. 2 is a top plan view with portions broken away and shown in sectionto disclose the joined ends.

Fig. 3 is a perspective view of the connecter or clip employed in joining the adja- Fig. 4: is a vertical transverse section of the cap flange.

Fig. 5 is a vertical edgeview of the con necter. Y

Fig. -6 is a vertical transverse sectional view of a screw type band and a closure disk associated therewith.

Screw cap flanges of ordinary construction are formed from a straight band of sheet metal which is bent to a ring-like formation, the ends of this band being then interlocked in such a manner that a shoulder or projection is formed upon the outer face at the point of union. projection is highly objectionable for numerous obvious reasons, among which is the liability of injury to the hands of persons removing capsembodying flanges so formed. Through the. constructionherein disclosed, the above and other objections are entirely overcome, and an annular flange having a perfectly smooth reliable joint isprovided.

In my improved construction, the band or attaching flange -is formedfrom a strip of metal, as is customary, such strip having its meetingends '6 bent or folded inwardly and substantially upon themselves to form a pair which are open at their opposite ends andhave'their closed. sides disposed in abutment Such shoulder or as shown in. Fig. As a result of this folding or bending operation, :I dispose for con-' tact with the hands of the user,- slightly rounded smooth surfaces 8, as shown in Fig.

.2,=thereby entirelyeliminating possibility of tion is concerned:

in ury in so :far as irregularsurface forma Injorder that the meeting ends of the band maybe rigidly interconnected, I employ a connecter or clip, including a substantially flat re'ctangularbody 9 having parallel hooks or. fingers 10 extending along longitudinally opposed edges and formedbybending portionsv inwardly toward each. other andin proximity .to'the body 9: In this connec ti on','it will be noted'that; these fingers 10 lVith the formation of threads 13, and the annular closure disk retaining lip or flange 1 1, the connecter or clip and the aforementioned extended portions 11 and 12, assume the shape shown in Fig. 4, wherein it will be noted that the extreme end portions 11 and 12 are snugly engaged over the opposed longitudinal edges of the 'band or flange, thereby presenting a continuous smooth surface and forming guards or shields for the ends of the folds, which otherwise would be exposed.

'As in other types of screw caps or plain bands, the lip or flange 14 is adapted toseat and retain a closure disk 15 of any preferred form upon the mouth of a jar or like container.

Certain changes in minor structural details may be resorted to within the scope of the appended claims.

What I claim is:

i 1. In a closure construction of the character set forth, a transversely divided annular band, opposed pockets at the meeting ends of the band, and a connecter rigidly securing the pockets together and arranged entirely upon the inner side of the band.

2. In a closure construction of the character set forth, a transversely divided annular hand opposed pockets on the inner side of the meeting ends of the band, and a conneeter rigidly securing the pockets together and arranged entirely upon the inner side of the band.

3. In a closure construction of the character set forth, a transversely divided annular band, opposed pockets at the meeting ends of the band, and a conneeter having opposed lingers engaged in and securing the pockets together and arranged entirely upon the inner side of the band.

4. In a closure construction of the character set :tortln a transversely divided annular band, opposed pockets on the inner side of the meeting ends of the band formed by bonding the meeting ends in opposite directions, and a connecter having opposed fingers engaged in the pockets and disposed upon the inner side of the band.

In a closure construction of the character set forth, a transversely divided annular band having its meeting end portions folded inwardly and substantially upon themselves to form a pair of opposed transversely extending pockets opening on the inner side of the band, and a connector rigidly securing the pockets together. i

6. In a closure construction of the character set forth, a transversely divided annular band having its meeting end portions folded inwardly and substantially upon themselves to form a pair of opposed transversely extending pockets opening on the inner side of the band, a eonnecter, and opposed hooklike fingers formed on the connector for engagement in the pockets.

7. In a closure construct-ion of the character set forth, a transversely divided annular band having a relatively wide body and an inturned disk retaining flange at one edge, opposed pockets extending transversely of the meeting ends of the body an opening on the inner side of the band, a connecter having fingers engaged in said pockets, and portions at the ends of the connecter being extended over the remote opposed edges of the body and flange.
